Happy New Year all!

I have dabbled with Linux for a few hours at most in the past, but I've now decided to get stuck into it. What with Windows being, er, not that fabulous. Anyway.... I got the Knoppix 3.6 Live CD distro and it always boots into the 2.4.x kernel. I'd like to know if it's possible to boot with the 2.6 Kernel on this distro, and how you do it. I want to do this because I've heard that there are some issues with my wireless card under the 2.4 kernel, and other posts say that they've had more success with the 2.6 version. So how do i boot the 2.6 kernel from the boot screen the CD gives me? Eventually, once i see it all works, I'll install Knoppix onto my Hard drive proper. Can't you tell I'm a n00b, it's probably dead simple....

Thanks in advance.
